- See Also:
setFixTxOffsets(boolean)
-
setFixTxOffsets
public void setFixTxOffsets(boolean fixTxOffsets)
When consuming records produced by a transactional producer, and the consumer is positioned at the end of a partition, the lag can incorrectly be reported as greater than zero, due to the pseudo record used to indicate transaction commit/rollback and, possibly, the presence of rolled-back records. This does not functionally affect the consumer but some users have expressed concern that the "lag" is non-zero. Set this to true and the container will correct such mis-reported offsets. The check is performed before the next poll to avoid adding significant complexity to the commit processing. IMPORTANT: At the time of writing, the lag will only be corrected if the consumer is configured withisolation.level=read_committed
andmax.poll.records
is greater than 1. See https://issues.apache.org/jira/browse/KAFKA-10683 for more information.- Parameters:
fixTxOffsets
- true to correct the offset(s).- Since:
- 2.5.6
